Is Classical Smog Is Also Called Reducing Smog?

Classical smog is mixture of smoke, fog and sulphur dioxide. Chemically it is a reducing mixture. It is also known as reducing smog.

Is classical smog oxidizing or reducing?

oxidising smog
Assertion :Classical smog is oxidising smog whereas photochemical smog is reducing smog. Reason: Classical smog occurs in warm, dru and sunny climate whereas photochemical smog occurs in cool humid climate.

What is called as reducing smog?

Classical smog is also called reducing smog as it acts as a reducing agent. The reducing character is due to presence of sulphur dioxide and carbon (soot) particles.

What do you mean by the term classical smog?

Classical smog is formed when there is high concentration of sulphur dioxide and particulate matter produced due to combustion of fuels. It occurs in cold and humid climate. It is also known as London smog or Sulphurous smog and causes dark brownish colour of atmosphere.

Which smog has reducing nature?

So, the correct answer is ‘London smog‘.

What causes reducing smog?

Drive less. Walk, bike, carpool, and use public transportation whenever possible. Take care of cars. Getting regular tune-ups, changing oil on schedule, and inflating tires to the proper level can improve gas mileage and reduce emissions.

Is photochemical smog oxidising?

Oxidation: Photochemical smog is also referred to as oxidizing smog. Oxidation reactions have been defined several ways. In terms of oxygen transfer, oxidation is a gain of oxygen. Oxidation can also be defined as a loss of hydrogen.

What are reducing and oxidising smog?

Photochemical smog is sometimes called as Oxidizing smog as it contains high concentrations of oxidizing agents like Ozone, HNO3 whereas Classical Smog is called Reducing as it contains high concentrations of sulphur dioxide, which is a reducing agent.

Why is London smog called reducing smog?

This smog is formed by the mixture of smoke, fog, and sulfur dioxide. This smog also acts as a reducing agent in atmospheric pollution. Therefore, it is also known as reducing smog.

Which of the following is not a component of reducing smog?

Solution : The oxidised hydrocarbons and ozone in the presence of humidity cause photochemical smog.
Hydrocabons `+O_(2),NO_(2),NO,O_(3) rarr` peroxide , formaldehyde, peroxyacetylnitrate (PAN) ,acrolein etc.
Hence chlorofluorocarbons are not common component of photochemical smog.

What is difference between classical smog and photochemical smog?

How is classical smog different from photochemical smog?

What is true about classical smog?

Classical smog is the smog that occurs in cold and humid climate and it contains compounds like sulphur dioxide, particulate matter that are compounds of reducing nature.

How are classical and photochemical smog different?

The key difference between classical smog and photochemical smog is that classical smog forms due to humid climate, whereas photochemical smog forms due to smoke coming from automobiles and factories. Moreover, classical smog forms in cool, humid climates, while photochemical smog forms in dry and sunny climates.

What are two ways that smog can be reduced?

On Days when High Particle Levels are Expected, Take these Extra Steps to Reduce Pollution:

• Reduce the number of trips you take in your car.
• Reduce or eliminate fireplace and wood stove use.
• Avoid burning leaves, trash, and other materials.
• Avoid using gas-powered lawn and garden equipment.

What reduces photochemical smog?

Photochemical smog has significant impacts on societies and living systems. Photochemical smog can be reduced by decreasing human reliance on fossil fuels.

What are the components of reducing smog?

To reduce photochemical smog, we should check at the primary level for a reduction in the use of hydrocarbons and nitrogen dioxide and at the secondary level for ozone and PAN. Catalytic converters when used in automobiles, reduce the emission of hydrocarbons and nitrogen dioxide.

What are the 2 types of smog?

At least two distinct types of smog are recognized: sulfurous smog and photochemical smog. Sulfurous smog, which is also called “London smog,” results from a high concentration of sulfur oxides in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal.

What are 10 ways to reduce smog?

10 Best Ways to Reduce Air Pollution

• Using public transports.
• Turn off the lights when not in use.
• Recycle and Reuse.
• No to plastic bags.
• Reduction of forest fires and smoking.
• Use of fans instead of Air Conditioner.
• Use filters for chimneys.
• Avoid usage of crackers.

What is meant by photochemical smog?

Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities. It tends to occur more often in summer, because that is when we have the most sunlight. Primary pollutants.

Is London smog oxidising or reducing?

Photochemical smog is oxidising in nature. And London smog is reducing in nature. Thus, the statement ‘London smog is oxidising in nature’ is false.

What is oxidizing smog?

Oxidizing smogs form when those emitted (or primary) pollutants are transformed through photochemical reactions into secondary pollutants, the most important of which are the strong oxidant gases, ozone and peroxyacetyl nitrate.
